Abstract

The invention discloses a signal processing system. The signal processing system comprises an input interface, a field programmable gate array module and at least two output interfaces. The field programmable gate array module receives an input signal of external equipment through the input interface. The field programmable gate array module is used for detecting the interface type of the input signal, converting the input signal into a standard signal in a preset format if the interface type is a preset type, and outputting the standard signal through a first output interface. If the interface type is a non-preset type, an input signal is output through a second output interface. According to the technical scheme, the input signals are selectively processed according to the interface types, the input signals of the preset type of interfaces are converted and then output, and the input signals of the non-preset type of interfaces are directly output from different output interfaces, sothat the input signals of the two types of interfaces are respectively processed, and the signal format conversion efficiency is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of signal processing, and in particular, to a signal processing system. Background technique [0002] In the process of collecting and integrating signals from different devices, the signals from different devices are required to have the same format for easy identification and processing. However, in practical applications, the formats of signals of different devices are usually inconsistent. For example, when signals from eye trackers and motion capture devices are input to the EEG for integration, the signals input from the eye tracker and motion capture devices have their own formats and time stamps. For example, the input signals may include cyclic signals, frequency Fixed continuous clock signals, continuous high-level signals, etc. These input signals in different formats cannot be directly recognized and used by the EEG, but need to be converted into standard format signals bef...
